Oh, on a final note, note the subject of your query. You assume it is a 
port drive problem rather than what you should be stating; that you are 
having a problem writing to the lcd "but i m not able to write data". 
Correctly state what your problem IS rather than what you think the 
problem might be "is it the problem of driving capcity or voltage levels".

Stating the actual problem will help you not only in EE but also in your 
personal life etc etc :)

BTW, logic high on an LCD is at least 2.2V so 3.3V is no problem.
